To all whom it may concern: V

Be it known that LRALPH J. MEYER, a citizen of the United 'States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented a new and useful Tater-Elevator, ofwhich the following is a specification. j

This invention relates to'hydraulic pumps of that type designed tobe partlysubmerged 1 within a water current and actuated-thereby for the purpose of forcing-a portion ofthe water to a desired point. f w e The object of the invention'is to provide a float-supported revoluble device designed'to be actuated by the current in which the device is supported, means being carried by said revoluble device for alternately taking up air and water and discharging the same.

into a distributing pipe.

A further object is'to provide a revoluble drive element which is of novel form and so mounted as to be protected from large'floating objects within. the frame.

A still further object is toprovide a machine of this character which is simple and durable in construction and which will efficiently operate in a current of practically any velocity. w

With these and other objects in new the invention consists of certain novel details of constructlon and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the re! formed of wood or other light materialand' constituting the base of a frame designed'to float in the current from which power is to be derived. The front and rear portions of these beams are connected by. arches 2 and? respectively which serve to rigidly connect the parts. e

Extending downwardlyfrom the middle portion of each'of the arched braces or' connecting devices2 and 3 are hangers land 5 respectively, the front hanger 4 constituting 1 Specification of Letters Patent. Patented Aug. 31, 1,909. a iieauon filed October 2, 1908 Seria1No.455 ,829.

' l a bearing for a trunnion 6 extending from the apex'of a conical rotor 7 having a spiral blade 8 arranged thereon and extending from the apex to the rear end of the rotor.

' Two concentrically arranged coiled pipes 9 are supported within the large end of the rotor and each of these pipes has its front end bent radially through the rotor and slightly curved at its terminus in a direction oppositeto that in which the rotor is designed to revolve,these terminals or intakes of the coilsbeing indicated at 10. The rear ends of the two coils merge into an outlet tube 11 whichprojects into and is designed to rotate within a sleeve 12 having an interior flange 13 constituting anend bearing for a cylindrical head 14 formed at the free end of the tube. It will be seen therefore that the when is free to rotate within the sleeve 12 but cannot move' longitudmally relative thereto, this beingdue to the fact that flange 13 prevents head 14 from moving in one direction while movement of the head in the opposite direction is prevented bya screw-plug 15, engaging the sleeve and having a passage 16 therein which opens into an elbow 17. The distributing pipe of the apparatus, and which is not designed to rotate, is to be attached to the elbow 17 From the foregoing description it will be apparent that the conical body 7 and the coils 9 carried thereby are free to rotatebetween the float members 1 while the coupling elbow 17. remains substantially station ary relatively thereto.

In order that logs and other obj cots-which might injure the device, may be prevented from passing between the beams 1 and striking the rotor, deflecting blades 18 are secured to the front ends of said beams.

In using the pump herein described the same is anchored in a current and the elbow 17 is connected to the distributing pipe not shown. The device is positioned so that the apex of the rotor will point in the direction opposite to that in which the current is flowing. The float members 1 will of course support the pump so that the body 7 will be only partly submerged. The action of the current upon the spiral blade 8 will result in the rotation of the body 7 and during this .movement thereofthe intakeslO willsuccessively move below and above the surface of the water. During their movement through the water they will collect a portion thereof and as time W111 be directed m the coils, After leaving the Water the inltakes wi'll be filled with air and this in turn will be directed into the coils. It will be seen therefore that alternate quantities of;

I water and air will be directed into the coils 7 andas said coils rotate with the body 7 the contents thereof will be moved along the coils to the coupling shown in Fig: 4 from Y 10 tributing pipe;

which they will be discharged into the disv-A'pu np such as here described is. particularly useful for irrigating purposes in that it .can be readily installed within water currents and, [b cause of itssimple construction,

cairhe used almost indefinitely Without re- :frgom'vvells, lakes, .etc.

- that is claimed is r V Agpump comprising converging floats, arched connections between the end. portions he o ha ge s dependingfrom said ca nections, a conical rotor journaled within the hangers and between the floats, said rotor extending partly below the floats, a deflector connected to the floats and disposed beyond one end of the rotor, a spiral blade upon the rotor and a tubular coil movable with the rotor and having an intake at one end and a discharge at its other end.

2. A pump comprising a float, and a rotor j ournaled upon the float and extending above and below the same, said rotor con- ,sisting of a hollow conical member revoluble about its longitudinal axis, a "spiral blade extending from the apex tothe base of said conicalmember, and .outer and inner concentric tubular coils within the conical member,

1 and'pitched reversely to the blade, each coil having a tangential intake portion extending through the conical member at a point between the ends of said member, said intakes being disposed at diametricalgly opposite points and extending in the direction of rotation of the conical member, and an outlei) tube, both of the coils opening into said- 1111: e; i
